Implementing assuring forward per hop behaviour class in web servers with dynamic scheduling and selective discards

摘要

This paper proposes an approach for services differentiation in web servers that preserves the network end-to-end quality of service (QoS) mapping in conformance to per hop behaviour assuring forward group. This novel approach uses dynamic scheduling techniques and selective discard of requests to provide a proportional service differentiation to web clients. A prototype was built over the Apache web server and measurements were carried out aiming to evaluate the approach, contrasting it with other traditional techniques of services differentiation.
